So.....kinda like pein's ability to see everything in the perspective of his rinnegan, Thr knight king can see through his minions hence no blind spots, and he would probably see his wife or someone he cares for come to his rescue only to die in the knight kings hands and he awakens some sort of power or due to his anger he somehow kills the knight king hence ending the long night but at the loss of someone he loves????
